Technical Field

[0001] This application relates to the field of seawater desalination devices, and in particular to an energy-saving seawater desalination device. Background Art

[0002] With the development of the marine economy, the demand for long-distance voyages of ships is increasing day by day. How to effectively obtain sufficient fresh water has become a major challenge faced by ocean voyages. Currently, seawater desalination methods include seawater freezing method, reverse osmosis method, distillation method, etc. Among them, the reverse osmosis method uses a semi-permeable membrane to pass water molecules in seawater and block salt molecules, so as to separate and obtain fresh water.

[0003] For example, the utility model patent with the patent publication number CN216141362U discloses a new type of reverse osmosis seawater desalination device, including a box body. Two groups of electric push rods are fixedly connected to the inner top wall of the box body. The bottom ends of the two groups of electric push rods are fixedly connected together with a sealing funnel. The bottom surface of the box body is fixedly connected with a sealing box. The bottom end of the fixed funnel is fixedly communicated with the upper surface of the sealing box. The inner bottom wall of the sealing box is fixedly connected with a treatment box. The inner side wall of the treatment box is fixedly connected with an activated carbon plate and a reverse osmosis membrane. The bottom end of the fixed funnel is fixedly communicated with a connecting pipe. The bottom end of the connecting pipe is fixedly communicated with a one-way valve. The upper surface of the box body is fixedly connected with a protection box. The inner top wall of the protection box is fixedly connected with a water pump. The output end of the water pump is fixedly communicated with a bent pipe. The end of the bent pipe away from the water pump penetrates through the box body and extends into the interior of the box body. The end of the bent pipe away from the water pump is fixedly communicated with a telescopic pipe. The bottom end of the telescopic pipe is fixedly connected with the top end of the sealing funnel. The input end of the water pump is fixedly communicated with a suction pipe.

[0004] Using the above-mentioned seawater desalination device, the use of power-driven devices such as electric push rods and water pumps requires a lot of electricity consumption, resulting in a high cost for long-distance voyages of ships, which needs to be improved. Summary of the Invention

[0005] In order to improve the problem that the use of seawater desalination devices requires a lot of electricity consumption, resulting in a high cost for long-distance voyages of ships, this application provides an energy-saving seawater desalination device.

[0006] An energy-saving seawater desalination device provided by this application adopts the following technical solutions:

[0007] An energy-saving seawater desalination device comprises a high-pressure cleaning machine, a reverse osmosis membrane arranged on the high-pressure cleaning machine, a solar panel and a battery, wherein the water inlet of the reverse osmosis membrane is connected to the water outlet of the high-pressure cleaning machine, the solar panel is electrically connected to the battery through a photovoltaic inverter, and the battery is used to supply power to the high-pressure cleaning machine, the high-pressure cleaning machine is provided with an elastic tube, the elastic tube is connected to the water inlet of the high-pressure cleaning machine, a movable plate is slidably connected to the high-pressure cleaning machine, the movable plate is located on the back side of the solar panel and slides close to or away from the solar panel, the elastic tube is located on the side of the movable plate close to the solar panel and is connected to the movable plate, an adjustment block is threadedly connected to the high-pressure cleaning machine, and the adjustment block is rotatably connected to the movable plate.

[0008] By adopting the above technical solution, the battery is charged by the solar panel, and the high-pressure cleaning machine is continuously powered by the battery charged by the solar panel, so that the high-pressure cleaning machine pumps seawater into the reverse osmosis membrane through high pressure for filtration to obtain fresh water. Solar energy is used instead of electricity, which is more energy-saving and environmentally friendly and reduces electricity consumption, which is conducive to reducing the cost of long-distance voyages for ships.

[0009] The increase in temperature will significantly reduce the power generation efficiency of the solar panel. When the temperature is high, the adjusting block can be twisted, and the adjusting block drives the movable panel to move closer to the solar panel, so that the elastic tube is close to the solar panel. During the operation of the high-pressure cleaning machine, the seawater flowing in the elastic tube takes away the heat of the solar panel to achieve cooling, thereby improving the power generation efficiency of the solar panel. According to the degree of temperature rise of the solar panel, the adjusting block can be further twisted, so that the elastic tube is squeezed by the solar panel and the movable panel, increasing the contact area between the elastic tube and the solar panel, and further improving the cooling effect of the elastic tube on the solar panel. If the temperature is low, the adjusting block can be twisted, and the adjusting block drives the movable panel to move away from the solar panel, so that the elastic tube is away from the solar panel, and the elastic tube recovers under the action of elastic force, reducing the aging of the elastic tube under long-term squeezing, which is conducive to extending the service life of the elastic tube.

[0010] Optionally, a plurality of connecting components are provided on a side of the movable panel close to the solar panel, and the plurality of connecting components are distributed in the transverse and longitudinal directions. The connecting components include a clamping band hinged on the movable panel, a positioning member 1 provided on the clamping band, and a plurality of positioning members 2 provided on the movable panel. The hinge axis of the clamping band is parallel to the rotation axis of the adjustment block, and the plurality of positioning members 2 are distributed circumferentially at intervals around the outer circumference of the clamping band. The positioning member 2 is used to cooperate with the positioning member 1 to position the clamping band. When the positioning member 2 cooperates with the positioning member 1 to position the clamping band, the clamping band and the movable panel are spliced to form a through hole for the elastic tube to pass through.

[0011] By adopting the above technical solution, after the elastic tube is damaged, the positioning state of the tightening belt can be released, and then the damaged elastic tube can be removed. Another new elastic tube can be taken, and according to the length of the elastic tube and the cooling requirement of the solar panel, the elastic tube can be arranged in any shape. Then, twist the tightening belt so that the tightening belt presses the elastic tube against the movable plate and positions the tightening belt through the cooperation of the corresponding positioning member two and positioning member one. After the positioning of the tightening belts on each connecting component passed by the elastic tube is completed, the connection and shaping of the new elastic tube on the movable plate can be completed. Only the elastic tube needs to be replaced, and other parts can be continuously used, reducing material loss, being beneficial to reducing the equipment purchase cost, and being adaptable to elastic tubes of different lengths with high applicability.

[0012] Optionally, the positioning member one includes a connecting portion provided on the tightening belt and a clamping portion provided on the connecting portion. A clamping groove for the positioning member one to be inserted into is formed on the positioning member two.

[0013] By adopting the above technical solution, after the tightening belt presses the elastic tube against the movable plate, insert the positioning member one into the clamping groove, and the tightening belt can be positioned by the clamping portion abutting against the positioning member two, with convenient and fast operation.

[0014] Optionally, when the positioning member one is inserted into the clamping groove, the connection part between the connecting portion and the tightening belt is located in the clamping groove.

[0015] By adopting the above technical solution, the connecting portion is limited by the inner wall of the clamping groove abutting against the connecting portion to keep the connection part between the connecting portion and the tightening belt in a straight shape, reducing the situation that the connection part between the connecting portion and the tightening belt is bent under the extrusion of the elastic tube, resulting in the tearing of the tightening belt and the positioning member one, which is beneficial to extending the service life of the tightening belt.

[0016] Optionally, the movable plate includes a plate body and an extension plate provided on the plate body. The extension plate is located above the solar panel. A communicated installation cavity and a cavity are formed in the plate body. A heavy ball is horizontally slidably connected in the installation cavity. An air outlet is formed on the extension plate. The air outlet is located on the side of the solar panel away from the plate body and is communicated with the cavity. A block is slidably connected in the cavity. The block fits the inner peripheral wall of the cavity and slides close to or away from the heavy ball. An elastic member is provided on the plate body. The elastic member pulls the block, so that the block has a tendency to approach the heavy ball.

[0017] By adopting the above technical solution, when the ship is sailing during the operation of the high-pressure cleaner, the ship and the objects on it will shake due to the ups and downs of the sea surface, causing the installation cavity to tilt, and the heavy ball moves under the action of gravity and impacts the block, causing the block to move closer to the air outlet, thereby pushing the gas in the cavity toward the air outlet. The pushed out gas blows away dust and other debris that fall from the surface of the solar panel, achieving self-cleaning and reducing the area of the solar panel surface that is blocked, thereby improving the efficiency of photovoltaic power generation.

[0018] Optionally, the direction of the air outlet forms an angle of 30-45° with the solar panel.

[0019] By adopting the above technical solution, the gas discharged from the gas outlet helps to blow away more debris on the surface of the solar panel, thereby improving the self-cleaning effect.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Using solar energy instead of electricity is more energy-saving and environmentally friendly and reduces electricity consumption, which is beneficial to reducing the cost of long-distance voyages. When the temperature is high, the adjustment block can be twisted to make the elastic tube close to the solar panel, and the seawater flowing in the elastic tube takes away the heat of the solar panel to achieve cooling, thereby improving the power generation efficiency of the solar panel. The contact area between the elastic tube and the solar panel can be adjusted according to the degree of temperature rise of the solar panel to further improve the cooling effect of the elastic tube on the solar panel. If the temperature is low, the adjustment block is twisted to make the elastic tube away from the solar panel, reducing the aging of the elastic tube under long-term extrusion, which is beneficial to extend the service life of the elastic tube;

[0022] 2. When the elastic tube is damaged, only the elastic tube can be replaced, and other parts can be used continuously, which reduces material loss and helps to reduce the equipment purchase cost. It can also be adapted to the use of elastic tubes of different lengths, and has high applicability;

[0023] 3. When the high-pressure cleaner is in operation and the ship is traveling, the gas in the cavity is pushed out toward the outlet through the cooperation of the heavy ball and the embedded block. The pushed out gas blows away the dust and other debris that fall from the surface of the solar panel, realizing self-cleaning and improving the efficiency of photovoltaic power generation.

The inner wall of the limiting groove 121 abuts against the limiting block 8 to prevent relative rotation between the plate body 61 and the connecting column 12.

[0037] See Figures 1-6 , the extension plate 62 is located above the solar panel 3 and is fixed to one end of the plate body 61. An installation cavity 611 is formed in the plate body 61. A heavy ball 9 is horizontally slidably connected in the installation cavity 611. Two cavities 612 are also formed in the plate body 61. The two cavities 612 are respectively located on both sides of the installation cavity 611 along the sliding direction of the heavy ball 9 and are communicated with the installation cavity 611. A plurality of air outlets 621 are formed on the outer side wall of the extension plate 62. The plurality of air outlets 621 are located on the side of the solar panel 3 away from the plate body 61 and are spaced along the length direction of the solar panel 3. The plurality of air outlets 621 are all communicated with the cavity 612. The orientation of each air outlet 621 forms an angle of 30-45° with the surface of the solar panel 3.

[0038] See Figures 1-7 , a fitting block 10 is slidably connected in each cavity 612. The fitting block 10 fits against the inner peripheral wall of the cavity 612 and slides close to or away from the heavy ball 9. An elastic member 13 is fixed on the plate body 61.

The two elastic members 13 are respectively located on both sides of the cavity 612. The elastic member 13 is a spring.

[0039] See Figures 1-8, on one side of the plate body 61 close to the solar panel 3, a plurality of connecting components 14 are provided. The plurality of connecting components 14 are evenly spaced in the transverse and longitudinal directions. Each connecting component 14 includes a tightening belt 141, a first positioning member 142, and a plurality of second positioning members 143.

The first positioning member 142 includes a connecting portion 1421 and a clamping portion 1422. The connecting portion 1421 is fixed to the other end of the tightening belt 141, and the clamping portion 1422 is fixed to the side of the connecting portion 1421 away from the tightening belt 141. The plurality of second positioning members 143 are circumferentially and evenly spaced around the outer periphery of the tightening belt 141, and the second positioning members 143 are fixed to the plate body 61. A card slot 1431 is formed on the outer side wall of the second positioning member 143 away from the plate body 61. The card slot 1431 is for the first positioning member 142 to be inserted. When the first positioning member 142 is inserted into the card slot 1431, the connection portion between the connecting portion 1421 and the tightening belt 141 is located in the card slot 1431, and a through hole 15 for the elastic tube 5 to pass through is formed by splicing the tightening belt 141 and the plate body 61.

In this embodiment, the material of the tightening belt 141 is suede, which has the ability of deformation, and the second positioning member 143 is a positioning block.

[0040] In actual use, when the elastic tube 5 is damaged, the first positioning member 142 can be moved to take out the first positioning member 142 from the card slot 1431 to release the positioning state of the tightening belt 141. Then, the damaged elastic tube 5 is removed, and a new elastic tube 5 is taken. The elastic tube 5 is placed between the hinge point of the tightening belt 141 and the second positioning member 143.

By the clamping portion 1422 abutting against the inner wall of the card slot 1431, the tightening belt 141 can be positioned. At this time, the elastic tube 5 is located in the through hole 15. Then, after the positioning of the tightening belts 141 on each connecting component 14 through which the elastic tube 5 passes is completed, the connection and shaping of the new elastic tube 5 on the movable plate 6 can be completed.

[0041] The implementation principle of an energy-saving seawater desalination device in an embodiment of the present application is as follows:

[0042] The solar panel 3 charges the storage battery 4, and then the storage battery 4 charged by the solar panel 3 continuously supplies power to the high-pressure cleaner 1, so that the high-pressure cleaner 1 pumps seawater into the reverse osmosis membrane 2 through high pressure for filtration to obtain fresh water. By using solar energy instead of electricity, it is more energy-saving and environmentally friendly and reduces power consumption, which is beneficial to reducing the cost of long-distance voyages of ships.

[0043] The increase in temperature will significantly reduce the power generation efficiency of the solar panel 3. When the temperature is high, the adjusting block 7 can be twisted, and the adjusting block 7 drives the movable plate 6 to move closer to the solar panel 3, so that the elastic tube 5 is close to the solar panel 3. During the operation of the high-pressure cleaning machine 1, the seawater flowing in the elastic tube 5 takes away the heat of the solar panel 3 to achieve cooling, thereby improving the power generation efficiency of the solar panel 3.

[0044] The adjusting block 7 can also be further twisted according to the degree of temperature rise of the solar panel 3, so that the elastic tube 5 is squeezed by the solar panel 3 and the movable plate 6, thereby increasing the contact area between the elastic tube 5 and the solar panel 3, and further improving the cooling effect of the elastic tube 5 on the solar panel 3.

[0045] If the temperature is low, the adjusting block 7 can be twisted, and the adjusting block 7 drives the movable plate 6 to move away from the solar panel 3, so that the elastic tube 5 is away from the solar panel 3. The elastic tube 5 recovers under the action of elastic force, which reduces the aging of the elastic tube 5 under long-term extrusion and is conducive to extending the service life of the elastic tube 5.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
